Interface system for automates

In a modern production line, quality data will be generated by various kinds of automatic inspections.
More und more zero defect requirements of the customers determine 100% control, which can only be fulfilled for
series by automates.

But also mass of Q-data can be generated by systems likes coordinate measuring equipment,
spectral analysis, SPC places etc...

iQ-MESSDAT is capable, to receive all these Q-data and handles them in various ways.

Basic functions

simultaneous support of several foreign systems with different interfaces

provision of a very simple but efficient interface

different ways to receive Q-data

handlingof several additional information

controlled limitation of not so relevant data

Data processing and storing is handled by use of the inspection order structures. There is no
difference between the handling of Q-data, which have been entered via directly connected tools or via iQ-MESSDAT; e.g.

decision use about produced lots

evaluation

data correction etc.

Data communication

The different forms if data transfer are shown in the table:

transport via ASCII-files with a transformation

transport via SQL-interface with a transformation

transport without transformation directly into the target-ASCII-file

transport directly into the SQL-tables of iQ-MESSDAT

further combination are possible

Handling of stored Q-data

background processing with high priority

avoiding of data queues

while process interruptions no loss of data

Kinds of Q-data

variable/quantitative measured values

attributive/qualititative failure information

the structure of the inspection order can completely be used

the inspection order can be generated automatically just before storing the first data

minimum requirements for unique assignment

order No.

shop order No.

character identification

values

Q-data are stored additionally in two further tables which are not part of the tables of the inspections order.
The first table (table with measured values) consists of the mostly used data. The second table (appendix table)
consists of data, that are normally not part of measurings produced by automates

Table with measured values

part No.

inspection order No.

character No.

Q-data (variable, attributive)

data, time of inspection

inspector

marking, whether initial value or correction after second trial

Appendix table

serial No.

machine, tool, cave

charge

shift

failure mode, -cause, -result

component

process step

causing cost center

causing part No.

inspection plan, index

events

Data discriminator

If you make 100% inspections for several characters, a mass of data will be produced. Normally some of these
characters are under control, which means that the measures are not as important as those of critical processes
In this case the interest is nor to high and the data shouldnt saved totally, only sampling is representative enough.
iQ-MESSDAT has a discriminator, which allows the suppression of uninteresting data. The targets of importance can be
influenced while data transferring
